Why is this a wonder of the ancient world?
We can say that the Colossus of Rhodes is part of the seven wonders because of its exemplary vastness. Moreover, it should well be realized that this Greek monument is the result of a very huge technical prowess which is characterized, amongst other things, by the use of terra cotta moulds necessary to the casting of the colossus. According to the legend, Charas of Lindos committed a suicide when he discovered an error in his calculs, error that one of his assistants had to correct.
